Standing Seam Machine

A standing seam machine is used to manufacture standing seam metal roofs. The working principle of a standing seam machine is identical to that of a corrugated roll forming machine. They are both used to produce the constructional materials except that the configurations of the end products are different. The corrugated roll forming machine creates closely spaced wave-like configurations on a metal sheet while the standing seam machine creates wider spaced ridges on a sheet metal. These machines apply cold metal forging techniques for mass production of parts in a rapid pace.

Standing Seam Metal Roofs

The standing metal roofs are the metal sheets with special patterns on the surface. They are sometimes considered a type of corrugated metal roofs which also have particular surface designs. Regardless of the pattern designs, these types of constructional materials are made with the cold metal forging machines that are designed to process sheet metals. The longevity of these constructional materials is significantly longer than the typical materials.

Advantages of Standing Seam Metal Roofs

The good quality standing seam metal roofs are expected to last over decades. Based on the manufacturing process and the standing seam machine that is involved, the standing seam metal roofs can possibly last for up to half a century. The production of standing seam metal is simple and rapid; it is cost effective as a result.

In addition to its superior longevity, the corrosion resistance and fire resistance also makes the standing seam metal roofs preferable. They are used commonly in Texas and California where the wildfires are an issue in certain seasons of the year. The standing seam metal roofs are resistant to cracking and shrinking; therefore, they are durable and reliable as a part of the construction.

Manufacturing Process of Standing Seam Metals

The standing seam metals are formed with a standing seam machine. The manufacturing process consists of several steps from the feeding of the sheet metal to the collection of the end products and the standing seam machine is only a part in the line. The four basic steps of standing seam metal forming are de-coiling, standing seam machine forming, cutting and stacking. The standing seam forming can be either performed in the factory or the whole production line can be brought onto the exact constructional site as well. The on-site roll forming equipment is similar to that in a roll forming factory and the manufacturing process is not much different though.


Before the sheet metal is process, it is coiled on a wheel. The sheet metal can be wide or it can be narrow in width based on the actual requirement. Once the sheet metal is fed into the standing seam machine, the metal sheet on the wheel will be de-coiled constantly and fed into the roll forming machine. In most cases, the sheet metal does not need to be leveled after it is uncoiled while in some rare cases it needs to pass through a leveling device before it is fed.

Standing Seam Roll Forming

In a standing seam machine, there is usually a set of dies or rolls. When the sheet metal passes through the dies, the material is deformed into the desired shape based on the configuration of the dies; in this case, the material is formed into standing seam metal panels. The cross section of the sheet metal is formed based on the way the dies or rolls are disposed in the machine. With different disposition, the end surface pattern of the material may vary.


The cutting of the formed metal panel is also referred to as shearing. At this stage, the forming of the standing seam metal is completed and the full-length metal panel needs to be dissected into a shorter, desired length. A hydraulic cutting press is responsible for the shearing work. The press incorporates with a computerized control unit to perform the work; the control unit sets the desired length and the cutting press executes the cutting work. After the material is cut into shorter metal panels, they will be sent to the stacking table.


If it is an on-site portable roll forming production line, the standing seam metal panels will be collected and assembled by the construction personnel right after they are cut. The process can be stopped anytime when the panels are enough for construction. Otherwise, the metal panels will be collected and stacked at the terminal of the production line. The whole roll forming process is efficient. It takes literally seconds to complete the production process from de-coiling to stacking.
